3. Problem description:
An error existed in the authorization checks in the version of cyrus-sasl
shipped with Red Hat Linux 7. Due to this bug, users who had been
successfully authenticated could be allowed access to resources even if the
system had been configured to deny these users access.
Versions of cyrus-sasl included in previous releases of Red Hat Power Tools
did not implement this function and are not affected by this bug.
4. Solution:
For each RPM for your particular architecture, run:
rpm -Fvh [filename]
where filename is the name of the RPM.
5. Bug IDs fixed (http://bugzilla.Red Hat.com/bugzilla for more info):
